Att All Builders/Plumbers!

Was sitting the other day, and decided that new offices would be nice, so have started digging the foundations for a new pub, offices, patio, bathroom, workshop, shower, toilet, little kitchen, new bedroom, new boundry wall......i sit too much

anyway, am doing this myself (okay not like spade in hand..hired help)

The question is, during the excavation on the office side...discovered that there is a 150mm storm water drain which will go through/intersect the foundation in 3 places. During the dig on the bedroom side, discovered similar thing but sewage pipe....

Our local regulations specify that these sort of piping needs to be encased in concrete for the total distance underneath the building.
But please check with your local council to find out if your regs differs.

I do not think you need to worry about crushing as this is VERY unlikely if you take the forces exerted on the pipe.
Just in case my previous post is not clear......... The whole pipe needs to be encased ALL the way from where it enters the foundation till where it exits again including underneath the floor. If I remember correctly the encasement I had to do was 500x500 mm around the pipe.

And be careful that after you have encased it the concrete does not shear the pipe off where it meets the soil.

It would be more sensible to divert it around the outside of the foundation.
